I had neuropathy in my feet and hands as a result of Oxaliplatin for my colon cancer chemotherapy. I took L-glutamine, 500 mg daily. I noticed a difference in about a week and after a month it was virtually gone. I finished the bottle and haven't had any problems since.
I had problems also with cold - I keep my feet covered, used gloves when handling cold/frozen items. Drinking cold beverages was a problem also.
The cold sensitivity has also subsided. Good luck
